In Intel® MAX® 10 devices with package U324, some of the I/O pins are getting pulled to GND after the speed mode SOF file is being configured into the device.
User will observes that certain I/Os are being pulled to LOW instead of being tri-stated during POF file programming into the internal flash using Intel® Quartus® Prime Programmer.
This is due to the speed mode SOF file is not compatible with the new Ordering Part Number (OPN).
User can apply a patch (for Intel® Quartus® Prime 20.1 Standard Edition) to correct the corresponding I/O state to tri-state. Alternatively, user can execute the POF file programming without speed mode selection (enabling real-time ISP in Intel® Quartus® Prime Programmer).
